[−][src]Struct stdweb::Mut

pub struct Mut<T>(pub T);

A wrapper for passing FnMut callbacks into the js! macro.

Just like when passing regular Fn callbacks, don't forget to drop() them on the JavaScript side or else the closure will be leaked.

Examples

let mut count = 0;
let callback = move || {
    count += 1;
    println!( "Callback called {} times", count );
};
js! {
    var cb = @{Mut(callback)};
    cb();
    cb();
    cb();
    cb.drop();
}
